    • General Procedure for C-N Coupling Reactions of β-Bromostyrene and Heterocycle Copper(I) iodide (0.1 equiv) and Cs2CO 3 (2.0 equiv) were added to a screw-capped test tube. The tube was then evacuated and backfilled with argon (3 cycles, N,N- Dimethylformamide (2 mL, nitrogen-containing heterocycles (1.2 equiv; if liquid) and vinyl halide (1.0 equiv; if liquid) were added by syringe at r.t. The tube was again evacuated and backfilled with argon 3 cycles, The mixture was heated to 120 °C and stirred for 36-50 h. After cooling to r.t, the mixture was diluted with H2O, and the combined aqueous phases were extracted three times with EtOAc. The organic layers were combined, dried over Na2SO4, and concentrated to yield the crude product, which was further purified by silica gel chromatography, using PE and EtOAc as eluents to provide the desired product.
